It works during the bootup - before the OS loads - when its running in the firmware? Hell, what's it called? I almost wrote "when its in the BIOS" but I figure if I say that ya'll will make mincemeat out of my rear.

Then when it boots up and X windows is running, the mouse doesn't work. No cursor.

Keyboard works.

I tried another mouse and rebooted, same result.

I tried two USB mice with USB->PS2 converters and one genuine PS2 mouse.

I didn't put this in the software or hardware pages because I don't know if its a software problem or a hardware problem.

Workstation firmware is a minefield, isn't it . SGI has ARCS or the PROM (or PROM monitor) (ARC is the DEC Alpha NT firmware), Sun has the PROM or OpenBoot, Alpha (real Alpha, not the NT stuff) has SRM or the Console (VAX is the Console as well), Apollo has md (Mnemonic Debugger) or the debugger, HP has PDC (Processor Dependant Code??), and Itanium has EFI. Cursed and ridiculed be he who confuses them!
